“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.
For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.
One of the oddest effects comes from the now famous“memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神经元突触） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid.

A．they are not sure whether mobile phones can cause memory loss

Walter Wetzel had met Ryan Lamantia nearly eight years ago in a hospital waiting room. Both were very sick——Ryan with brain cancer, Walter with leukemia (白血病). Ryan, who was 3 at the time, began making silly faces at Walter and chatted about going home to change into his Teenage Mutant Ninja Turtles costume. Several days later, Ryan moved to another hospital. Though they saw each other only a handful of times after that, Walter never forgot Ryan.
"He inspired me to fight against my cancer," said Walter, now 17, a football player. Then one day, Walter saw a Teenage Mutant Ninja Turtles shirt at a mall, which made him decide to search out Ryan. Back home, Walter typed in "Ryan Lake in the Hills brain cancer" on his computer, and a link to a Facebook page for Ryan came up. But, the news was shocking.
Ryan had died on Sept. 8, 2005. He was 6. The Facebook page was for the Ryan Lamantia Foundation, a non-profit organization that Ryan's family formed after his death to raise money for brain cancer research.
Walter left this message right away: ."Ryan is my hero. My trips to the hospital were always horrible, until the day I met Ryan."
Ryan's mom's eyes were filled with tears as she read Waiter's message. "We always knew Ryan was special, but to hear it from somebody else, it really means the world to us," Lamantia said.
Walter wasn't the only person who was greatly impressed with Ryan.
"He was a little superhero," said Wendy Stellpflug, a nurse at Children' s Memorial Hospital. "Ryan always kept his spirits high, even after he suffered hearing loss and experienced 14 operations."
"Ryan didn’ t let his illness stop him. He always had a smile on his face," said Dr. Stewart Goldman, the doctor who treated Ryan.
Walter and his family have been in touch with the Lamantias for the past few weeks. And last week, they met for the first time since Ryan's death. The families told stories of being affected by cancer so young and Walter expressed his hope to volunteer with Ryan' s foundation.

We know that hugs make us feel easy inside. And this feeling, it turns out, could actually ward off stress and protect r the immune (免疫) system, according to a new research from Carnegie Mellon University.
It’s a well-known fact that stress can weaken the immune system. In this study, the researchers sought to determine whether hugs----like social support more broadly ----could protect individuals from the increased sensitivity to illness brought on by the particular stress that come with interpersonal conflict.
“We know that people experiencing ongoing conflicts with others are less able to fight off cold viruses. We also know that people who report having social support are partly protected from the effects of stress on psychological states, such as depression and anxiety, “the study’s lead author, psychologist Dr. Sheldon Cohen , said in a statement. “We tested whether awareness of social support is equally effective in protecting us from sensitivity to infection caused by stress and also whether receiving hugs might partially account for those feeling of support and thus protect a person against infection.”
In the experiment , over 400 healthy adults filled out a questionnaire about their perceived (感知) social support and also participated in a nightly phone interview for two weeks . They were asked the frequency they engaged in interpersonal conflicts and received bugs that day.
Then, the researchers exposed the participants to a common cold virus, and monitored them to assess signs of infection. They found that both perceived social support and more frequent hugs reduced the risk of infection associated with experiencing interpersonal conflict. Regardless of whether or not they experienced social conflicts, infected participants with greater perceived social support and more frequent hugs had less severe illness symptoms.
“This suggests that being hugged by a trusted person may act as an effective means of conveying support and that increasing the frequency of hugs might be an effective means of reducing the effects of stress,” Cohen said. “The apparent protective effect of hugs may result from the physical contact itself or hugging being a behavioral indicator of support and closeness. Either way, those who receive more hugs are somewhat more protected from infection.”
If you need any more reason to go wrap your arms around someone special, consider this: hugs also lower blood pressure, reduce fearsome around death and dying, improve heart health and decrease feeling of loneliness.

A．produce

B．increase

C．prevent

D．support

While you may think that being smart and talented would logically make someone successful in running a business, unfortunately, this is often not the case.
This problem starts back in school when the stressful “group projects” are first assigned .The smartest don’t want to risk their grade in the class by dividing the work equally and hoping that an average student does his part well. They just take over and do the whole project themselves.
And thus begins the smart-people work cycle. The smartest people do just about everything better than most everyone else until it comes to running a business. They are not better. A smart person who can’t stand someone else doing a job badly does everything himself. Then, he is stuck with the one-man band “job-business” and ends up not being able to grow. However, it is quite interesting and strange that some “slackers” ( a person who is lazy and avoids work) are better suited to be a business leader than the “smart” people.
Smart and talented people often have a gift for the unusual, complicated or different. They don’t like to follow the KISS principle (keep it simple, stupid), which is required to make a business succeed. Maybe you think the global presence of McDonald’s complex, but in reality, in the company, every single task is broken down into easy-to-follow steps and everything has been standardized. These successful companies have just a few smart enough people to run the majority of the tasks in a way that can’t be screwed up by their average employees. So, being smart or talented isn’t going to help you unless you can use those smarts to figure out a way to simplify those tasks that will make a business successful.
Another issue with the smart people starting businesses is that they often have the most to lose. The smarter you are, the more options you have available to you. You will be able to make a lot of money in various fields and have room in your career to become promoted. This means that when you start a business, you have a lot more to risk than those who are not equally smart. This is often referred to as the “golden handcuffs” dilemma.
So, don’t be surprised when the person “MOST Likely to Succeed” from high school ends up as an employee and it is one average student that finds success in his or her own business.
In group work, smart students often take over the whole project because they believe ____.

A．the work is not divided equally

B．they can perform better than others

C．the group projects are too stressful

D．average students are unwilling to participate

McDonald’s is used as an example to prove that ____.

A．a business calls for smart people’s talent

B．average employees can perform complex tasks

C．smart people are important for a successful business

D．simplified tasks are required for the success of a business

The underlined expression in Paragraph 5 refers to the situation where smart people ____.

A．have fewer options in a company

B．risk more when starting business

C．are unwilling to put money to a business

D．can have a good income in many different fields

What is the best title for the passage?

A．Potentials for Success

B．Bases for Business

C．The Ordinary Achieve Bigger Success?

D．Talent Means Successful Business?
